That sounds really great. I say that if he makes you laugh, gets along well with your friends, and above all treats you well, you are very lucky to have met him. Besides, you don't have to look at it as if it has to be serious. At the least you could come out of this with a friend, and we all know we can always use another friend!
So yes, go and have a great time, and celebrate the selling of your house!
